Fast screening of polycondensation catalyst, Determination of the kinetic data of catalyzed polycondensation in polyethylene terephthalate synthesis
Differential scanning calorimetry (DSC) belongs to the family of thermal analysis methods. In general thermal analysis is the determination of substance properties in dependence on temperature. Thermodynamic data (heat capacity, phase transition, enthalpy) and kinetic data can be determined by methods of thermal analysis. The greatest advantage of thermal analysis is the easy handling and the o...
متن کاملImmobilization of silver nanoparticles on polyethylene terephthalate
Two different procedures of grafting with silver nanoparticles (AgNP) of polyethylene terephthalate (PET), activated by plasma treatment, are studied. In the first procedure, the PET foil was grafted with biphenyl-4,4'-dithiol and subsequently with silver nanoparticles. In the second one, the PET foil was grafted with silver nanoparticles previously coated with the same dithiol. X-ray photoelec...
متن کاملConfinement-induced vitrification in polyethylene terephthalate
Dynamic mechanical thermal analysis performed on cold-drawn polyethylene terephthalate PET , cold crystallized annealed in the temperature interval 100–140 °C, reveals the presence of marginally glassy domains above the annealing temperature Ta. This suggests that the thermodynamic force driving crystallization causes the structural arrest of some noncrystalline domains. The latter thus need a ...
متن کاملPolyethylene Terephthalate May Yield Endocrine Disruptors
BACKGROUND Recent reports suggest that endocrine disruptors may leach into the contents of bottles made from polyethylene terephthalate (PET). PET is the main ingredient in most clear plastic containers used for beverages and condiments worldwide and has previously been generally assumed not to be a source of endocrine disruptors. OBJECTIVE I begin by considering evidence that bottles made fr...
متن کامل1 Coarse - Grained Molecular Dynamics Simulation of Polyethylene 2 Terephthalate ( PET )
9 ABSTRACT: A coarse-grained (CG) model of poly(ethylene terephthalate) (PET) was developed and 10 implemented inCGmolecular dynamics (MD) simulations of PET chainswith degree of polymerization up to 11 50. TheCGpotential is parametrized to structural distribution functions obtained fromatomistic simulations 12 [ J. Phys. Chem. B 2010, 114, 786] using an inversion procedure based on theOrnstein...
